By default, packages fully using GNU <CODE>gettext</CODE>, internally,
are installed in such a way as to allow translation of
messages.  At <EM>configuration</EM> time, those packages should
automatically detect whether the underlying host system already provides
the GNU <CODE>gettext</CODE> functions.  If not,
the GNU <CODE>gettext</CODE> library should be automatically prepared
and used.  Installers may use special options at configuration
time for changing this behavior.  The command <SAMP>&lsquo;./configure
--with-included-gettext&rsquo;</SAMP> bypasses system <CODE>gettext</CODE> to
use the included GNU <CODE>gettext</CODE> instead,
while <SAMP>&lsquo;./configure --disable-nls&rsquo;</SAMP>
produces programs totally unable to translate messages.

Internationalized packages have usually many <TT>&lsquo;<VAR>ll</VAR>.po&rsquo;</TT>
files.  Unless
translations are disabled, all those available are installed together
with the package.  However, the environment variable <CODE>LINGUAS</CODE>
may be set, prior to configuration, to limit the installed set.
<CODE>LINGUAS</CODE> should then contain a space separated list of two-letter
codes, stating which languages are allowed.
